RAIL-CLAMPING DEVICE FOR THlN OR SHEET METAL RAILWAY-TIES.

SPECIFICATION forming part of Letters Patent N 0. 671,607, dated April9, 1901.

Application filed August 15,1900. Serial No. 26,923. (No model.)

To all whom, it nuty concern:

Be it known that I, CY RUs OLDROYD, a citizen of the United States,residing at Morrisdale Mines, in the county of Clearfield and State ofPennsylvania, have invented a cerrain new and useful Improvement inRail- Clamping Devices for Thin or Sheet Metal Railway-Ties,of which thefollowing is a specilication.

My invention relates to rail-clamping devices for thin or sheet metalrailway-ties.

My invention is illustrated in the accompanying drawings, Wherein Figure1 is a side elevation of a tie with a section of rail secured inposition according to my invention, with the parts shown in twopositions by means of dotted lines. Fig. 2 is a longitudinal sectionthrough the same. Fig. 3 is a plan View of the same. Fig. 4: is a sideelevation of a modification.

Like parts are indicated by the same letter in all the figures.

A is a thin or sheet metal railway-tie, and the same may be made ofpressed steel. In that form of my invention which is shown in Figs. 1,2, and 3 this railway-tie has certain holes and lugs struck on it,preferably by means of a die at one action. These parts consist of theflange B, the side lugs O O, the bolthole D, and the slot E.

F illustrates a section of the rail.

G is the rail-clamp, which has the two side lugs O to engage the lug O,the flange B opposite the flange B, the bolt-hole for the bolt D and theinner downwardly-depending wedge-shaped projection H. This clampingdevice may be made of the same material as the tie and may be made andformed in the same manner.

The application of the clamping device to the tie is readily seen byreference to Fig. 1, where in dotted lines the clamp is shown in thefirst position of application. Now if the outer end of the clamp beforced downwardly toward the tie it is evident that the lug C will takeunder the lugs O, the flange B will overhang the flange of the rail, andas the outer end of the clamp is further depressed the wedge or areshaped piece H will engage the outer end of the slot E and force theclamp toward the rail, whereby all the parts will be firmly forcedtogether in position to securely clamp the rail to the tie. The bolt Din this case screw-threaded into the parts, is then set in position. Thebolt, however, can be attached in any desired manner, as by a nut on thebolt instead of a screw-thread on the tie.

The modification shown in Fig. 4 differs principally in this, that thearc-shaped or wedge-shaped portion of the clamp is on the outside, andinstead of the slot against the end of which it is intended to bear thepin J is substituted. The action, however, is substantially the same ineach case.

It will be evident that considerable modification can be made in theform of this device, and Ihave simplyshown these two forms to give agood illustration of the general nature of my invention without desiringthereby to limit myself to the particular form shown.

I claim 1. A clamp for railway-rails, comprising a flange on the tie tooverhang one of the railflanges, sidelugs on the tie below the railand amovable clamping device, having lugs adapted to take under the side lugson the tie and a flange adapted to overhang the other flange of the railand an are or wedge shaped projection adapted to take against a portionof the tie and, when the clamp is pushed into position by its wedgingaction, to force the parts securely into place.

2. A clamp for railway-rails, comprising a flange on the tie to overhangone of the railway-flanges, side lugs on the tie below the rail and amovable clamping device, having lugs adapted to take under the side lugson the tie and a flange adapted to overhang the other flange of the railand an are or wedge shaped projection adapted to take against a portionof the tie and, when the clamp is pushed into position by its wedgingaction, to force the parts securely into place, and a securing device tohold the clamping-piece in such final position.

3. In a rail-clamping device, the combination of a sheet or thin metaltie, having a flange on the top and projections on the side, with aclamping-piece, having lugs and a flange at its forward end to coactwith the lugs ar'id flanges on the tie, and a slot in the tie and adownwardly-depending wedge or are shaped projection on theclamping-piece adapted to pass into said slot.

4. In avail-clamping device, the eembinaadapted to pass into said slot,said several tion of 2'; sheet or thin metal tie, having a flanges,lugsand' projections formed respec- 10 with a clamping-piece, havinglugs and a flange at its forward end to coact with the lugs and flanges0n the tie, and a slot in' the Witnesses:

tegrai therewith.
